We hope to try SSR this January. Hard to compare without trying it, but we have stayed at the old Disney Institute Villas (what was original to the SSR site) and enjoyed the location very much.
Agree that each resort (DVC and non-DVC alike) will appeal to certain guests more than others. For some it may be the price, some the theming, some the location, some the amenities, etc. Thank goodness for variety!
We have our favorites, but have enjoyed every WDW stay. We found something nice about every resort we have tried.
